OFFICIAL EXPLANATIONProject SC Butler: Sentence Correction (SC2)
THE PROMPTQuote:
In the mythologies of Greece, China, Scandinavia, and
of the ancient Americas, ravens and their kindred species have been regarded as highly intelligent tricksters, which has been further supported by scientific fieldwork.
• List mistake
→ In a list, a modifying word such as OF comes before only the first item (and "distributes" across to the other list items) or comes before
all the list items.
→ In other words, to maintain parallel structure,
of should not be repeated before
the ancient Americas because
of is not repeated before the other two list items,
China and
Scandinavia.
GMAT writers rarely repeat common list words and follow the convention of placing the common word before the first element only.
• IDIOM
The correct idiom is
regarded as and not
regarded to be. • Meaning
→ It is
the portrayal of the ravens as highly intelligent tricksters that has been further supported by something— not the ravens themselves.
THE OPTIONSQuote:
A)
of the ancient Americas, ravens and their kindred species have been regarded as highly intelligent tricksters,
which has been further supported
• LIST - lacks parallelism.
→ The word
of should be placed before only the first list item or before all four list items.
• WHICH: to what does
which refer?
→
which is a pronoun that must refer to a noun and that cannot refer to an entire previous clause
ELIMINATE A
Quote:
B) the ancient Americas, ravens and their kindred species have been regarded as highly intelligent tricksters, a portrayal that has been further supported
• I do not see any errors
• The sentence uses the correct idiom,
regarded as.• The sentence also gets the parallel structure correct by not repeating the
of before the words
ancient Americas.KEEP
Quote:
C)
of the ancient Americas, ravens and their kindred species have been
regarded to be highly intelligent tricksters,
further supported• List parallelism is broken
→ Same problem as that in option A
• Idiom error
•
Regarded to be is not idiomatic.
Regarded as is correct.
• Modifier error ("further supported by scientific fieldwork")
→ It is not clear what
further supported is modifying.
→ On the GMAT, past participles (verbED words), whether or not preceded by a comma, modify the noun immediately before the past participle (verbED word).
"Further supported" does not modify tricksters. In fact, it's not clear what "further supported" modifies.
ELIMINATE C
Quote:
D) the ancient Americas, ravens and their kindred species have been regarded as highly intelligent tricksters,
ones further supported
•
The ones refers to ravens and their kindred species, which makes no sense.
How are the ravens "supported by" field study?
ELIMINATE D
Quote:
E) the ancient Americas, ravens and their kindred species have been
regarded as highly intelligent tricksters and as further supported
• Illogical meaning
The use of the
and after the comma distorts the meaning of the sentence by suggesting that the
ravens have been regarded as
two things.
ELIMINATE E
The best answer is B.
COMMENTSMost of these answers are excellent.
Kudos to all.
